Quality assurance is a technique of testing and monitoring a product to make sure that the finished product is created without defects. In physical manufacturing, QA testing may include failure testing, statistical testing control and other industry-specific practices.
Many of the people get confused when it comes to quality assurance and quality control and testing. The differences that can be noted are:
Quality Assurance- These activities include and make sure the implementation of processes, procedures and standards in context to validation of developed software and intended requirements. Focuses on processes and procedures rather than conducting actual testing on the system. It is a process oriented activities.
Quality Control- This includes the activity that makes sure the verification of developed software with respect to documented requirements. This focuses on actual testing by executing the software with an aim to spot bug/defect through the implementation of procedures and process. It is a product oriented activities.
Testing– It includes an activity that makes sure the identification of bugs/error/defects in a software. Focuses on the actual testing. It has product oriented activities.
What are the best practices of QA testing?
- Test one thing at a time: tests should have clear objectives. Each test should specialise in a feature or check out things like interface or security.
- Understand the types of testing on offer- There are lots of different types of tests from load testing to user acceptance testing (UAT)- so make sure you understand the differences and how to use them.
- Use regression tests- Testing a main feature once isn’t enough. New additions to the code repository can interfere with features that previously passed tests.
- Report and track bugs- Determine how bugs will be reported and what kind of data is needed. Will you use an open-source bug tracking tool or build one’s specifically suitable for workflow.
- Leverage analytics- Decide which QA metrics to find. It keeps records of every test conducted and uses this data to determine where bugs are likely to occur. This data will assist you to develop new tests that address problem areas.
- Choose the right environment for tests- we should try to cover a wide range scenarios, including different devices, OS and user profiles.
- Use unit and integration tests-Unit testing will isolate each component of your app while assess how well each subsystems work. Run unit tests in parallel to save time, but don’t move onto integration tests until you have made sure that individual components work.
Including the agile methodology into software testing
Agile methodology makes sense in the context of developing mobile apps given that these products typically have short development cycles and mobile users have extremely high expectations regarding functionality, quality and frequent updates. With these agile methodologies, QA testing is a part of the design and development processes than being a separate phase. The test results are included directly into the design and development processes and quality becomes a guiding principle.
This is a collaborative approach that needs designers, developers, the QA team and sometimes even users to speak or work together. In order to facilitate collaboration you can use a single repository for the app code.
